Example Code
This example code calculates the [Remaining Life] value of the cabinet fan for
the first power structure. For frames 9 and 10, use similar logic for the other
cabinet fans. Use similar logic to calculate the [Remaining Life] of the heatsink
fans and the internal stirring fans.
1. Use a timer instruction to set a sensible time interval for reading the data.
See
Figure 79 .
